“…All the fibers mentioned above are air holes or liquid-filled air holes. A liquid-filled hybrid structure of DCC-DCPCF with the negative dispersion value being −40400 ps/(nm • km) at 1550 nm and an inner core high-doping DCC-DCPCF with the negative dispersion value being −51625 ps/(nm • km) at 1550 nm were reported by Hsu et al [10,11]. Partha et al designed a DCC-DCPCF with liquid-filled air holes-the negative dispersion value has reached −52100 ps/(nm • km) at 1550 nm-and analyzed the influence of the material on the phase matching wavelength (λp) and dispersion value at different temperatures [12].…”

An all-solid dispersion-compensating photonic crystal fiber based on mode coupling mechanism in dual-concentric core has been proposed. The mode coupling characteristics, dispersion, confinement loss of the fiber, and the influence on dispersion of some structure parameters are simulated by full-vector finite element method. By using the relationship between phase matching wavelengths and coupling strength with the change of fiber microstructure parameters, an all-solid dual-concentric-core dispersion-compensating photonic crystal fiber is presented. The structure parameters on dispersion characteristic are investigated. The results demonstrate that the proposed fiber has a large negative dispersion value 8465 ps/(nm·km) at 1550 nm. The effective mode area and the splicing loss to the standard single mode fiber are 12.8 μm2 and 1.89 dB at 1550 nm, respectively. At 1550 nm, the confinement loss is less than 1 × 10−3 dB/km and the bending loss with 2 cm bending diameter is less than 1 × 10−2 dB/km.

“…for a wavelength range of 388nm as demonstrated in Fig dB/m. The advantage and relevant issues of liquid infiltration technique has already been investigated [21,[29][30][31][32]. Typical compositions of the liquids available with M/s Cargille Labs, USA, are Perfluorocarbon and Chlorofluorocarbon (not the types thought to affect the ozone) [25].…”

In this article, a new technique to attain a tunable parametric amplifier for application in the communication wavelength, based on near zero ultra-flat dispersion with PCF, has been explored. The chromatic dispersion profile and the corresponding ZDW of the optimized PCF can be well tuned to provide a wide gain spectrum in the communication wavelength just by changing the temperature of the fiber. A detail investigation reveals that the fiber retains its near-zero ultra flat nature when the temperature is increased by 2.5 0 C from the room temperature. While changing the temperature, the ZDWs can be well tuned, giving rise to a gain region of hundred of nanometer around the pumping wavelength by changing the temperature of the fiber externally.

“…This result indicates that the TOD effects of the two fibers can be cancelled in the vicinity of 1550 nm when the pulse passes through these two fiber segments with equal fiber lengths. For the purpose of estimating the efficiency and quality of pulse compression, the compression factor F C and the quality factor Q C can be defined as (11) where T C FWHM is the full width at half maximum (FWHM) of the compressed pulse, E total is the total energy of the compressed pulse, and E C is the pulse energy contained in the central part of the compressed pulse.…”

The three-core photonic crystal fiber (TC-PCF) is proposed to obtain large group-velocity dispersion (GVD) because of the coupling effects between the fundamental modes (FMs) of the central core and higher-order modes (HOMs) of the two side cores. The supermodes of the TC-PCF can provide concave anomalous-and normal-GVD profiles with large peak values at the maximum dispersion wavelengths (MDWs), which can be shifted in three wavelength windows of 1030 nm, 1550 nm and 1900 nm by properly tuning the refractive indexes of the cores or the air-hole diameters. Furthermore, the numerical results show that two segments of the TC-PCFs with large anomalous GVDs and opposite values of the third-order dispersion (TOD) can provide much higher efficiency of pulse compression than one segment of the TC-PCF. Additionally, the TC-PCFs with large normal GVDs can be used to stretch pulses due to their low nonlinearities and short fiber lengths.
